6. Trees for streets, ^Lreinies and Hoadsides. ~ T'Iiq 

 number of tree species suitable for street planting is 

 limited by the necessarily heavy restrictions, as to 

 height, spread, sewer-penetration and sidewalk-raising, 

 imposed by municipal street departments, in European

cities the first-named objections are overcome by means 

 of frequent and systematic pruning to a uniform stand- 

 ard; where this necessity can be obviated by the selec- 

 tion of trees whicli naturally keep within the desired 

 bounds, the labor of maintaining them in a sightly con- 

 dition is minimized and the result much more pleasing. 



For town streets not more than GO feet in width, it is 

 important to have trees that will not give too much 

 shade and prevent the rapid drying of the roadway 

 after showers, nor be so tall nor w^ide-spreading as to 

 obstruct the view and shut out sunshine, rendering the 

 adjacent houses dark, cold and damp. On this account 

 trees with narrow or pyramidal outline are in many 

 cases preferable to those with wide -spreading habit, 

 and, generally speaking, deciduous trees are more suit- 

 able than evergreen, although at the time of losing 

 their leaves they make more Jitter. Exception may be 

 made in favor of such evergreen species as certain 

 palms and cordylines, some acacias and a few other 

 species mentioned below. 



It is not wise to use trees of very rapid growth on 

 town streets; they soon become too lar^'e and reiinire 

 frequent trimming, which is usually equivalent to muti- 

 lation, and are likelv to interfere with sewers. 



It cannot be said that street planting in California 

 towns has, in most cases, been satisfactory. In spite of 

 the much larger variety of suitable material than is 

 ivailable in most of the states, there are few examples 

 rf good street-plantiDg to be met with. In most of our 

 trwns the eye is greeted with a few straggling trees, of 

 which perhaps not more than two are of one kind, re- 

 c lling Professor Waugh's apt simile of "nine mou- 

 strously <lilTerent buttons in a row down the front of a 

 Prince Albert coat." There nre many pleasing exceptions, 

 h twever, although few are entirely satisfactory. The rc-

 every occasion, and the object of this arti<de is to render
